Currently supported materials for ExOne® Systems.

Silica Sand

Silica sand is one of the most common varieties of sand in the world and is derived from quartz crystals. It is used for a wide range of applications, including the creation of molds and cores for industrial castings. The advantage of using a common material such as silica sand for 3D printing is that it requires no changes at the foundry. Additionally, when used with furan binder, it is considered a “no bake” product, which means that printed silica sand molds and cores are immediately ready for casting.

420 Stainless Steel / Bronze Matrix

ExOne® 3D Printed 420 Stainless Steel infiltrated with Bronze is a matrix material composed of 60% stainless steel and 40% bronze infiltrant. This material offers good mechanical properties, is available in both an annealed and non-annealed condition, is able to be machined, welded and polished, and offers excellent wear resistance.

316L Stainless Steel

316L Stainless Steel has broad applications in the automotive, medical and general industry markets, used to produce a range of products, including surgical tools, metallic filters, pumps, impellers and structural automotive parts. 316L Stainless Steel is known for its excellent mechanical and corrosion resistance properties and cost-effectiveness.

Denim Jacket Denim Jacket 17-4PH Stainless Steel

17-4PH Stainless Steel has broad applications in the automotive, medical and general industry markets, used to produce a range of products, including surgical tools, metallic filters, pumps, impellers and structural automotive parts. 17-4 Stainless Steel is known for its excellent mechanical and corrosion resistance properties and cost-effectiveness.

Ceramic Beads

Ceramic Beads is a spherical ceramic (synthetic) sand used in foundry operations for the creation of sand molds and cores. It is comprised of aluminum silicate and exhibits excellent refractory properties, high permeability and thermal expansion. Gases are readily dispersed, reducing the potential for porosity in the casting. Cerabeads is compatible with all binders and is especially recommended for casting steel alloys or printing cores subject to high thermal stress conditions.

IN Alloy 625

ExOne
® 3D Printed Alloy IN 625 material is a nearly full dense, austenitic nickel-chromium-based superalloy. This material offers excellent mechanical properties both at extremely high and low temperatures. It also exhibits high resistance to oxidation at elevated temperatures of up to 1050°C. Good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis makes possible the construction of thin structural parts with high heat transfer capabilities.

IN Alloy 718

Commonly used for components in the aerospace, chemical and energy markets, with applications including gas turbine blades, filtration and separation, heat exchanger and molding processes, the alloy is desirable due to its oxidation and corrosion-resistant qualities, able to retain its strength even when subjected to extreme environments.

Iron / Bronze Matrix

ExOne
® 3D Printed Iron infiltrated with Bronze is a matrix material composed of 60% iron and 40% bronze infiltrant. This material offers good mechanical properties, is able to be machined, welded and polished, and offers excellent wear resistance.

Denim Jacket Jacket Denim Iron-Chrome-Aluminum

Offering superior properties as compared to the other alloys, Iron-Chrome-Aluminum alloys are widely used in electrical furnace, electrical oven, home appliance, electrical heater and infrared settings.

Chromite

Chromite sand is a naturally occuring spinel consisting of chrome and iron oxides. As a mold and core making sand, its properties enable the material to be utilized in heavy duty grey iron and steel foundries. Its high thermal conductivity gives it favorable chilling properties and low thermal expansion contributes to excellent dimensional stability. Used as a standalone material, or as an additive to silica sand, chromite allows for faster heat dispersion and results in finer microstructure of the metal and therefore a higher quality casting.

Cobalt-Chrome

Traditionally used in various fields where high wear-resistance is needed, including aerospace, cutlery, bearings and blades, Cobalt-Chrome alloy has recently received more attention for medical applications due to excellent resistant properties, high melting points and incredible strength at high temperatures.

Zircon

Zircon (a naturally occurring beach sand) is often used in foundries for the production of sand molds and cores to improve casting performance. It has a high thermal expansion coefficient, a melting point of 2500°C, and a Mohs hardness of 7.5. Zircon’s low thermal expansion rate, its high thermal conductivity and its non-wettability by molten metal make it and ideal mold and chill sand. It is also used to improve surface finish. Zircon can be 3D printed as a straight material or as a mixture with silica sand. Its usage as an additive creates faster heat dispersion and results in finer microstructure of the metal and a higher quality casting.

Bonded Tungsten

Developed in partnership with an ExOne customer, bonded tungsten has been qualified for use on the M-Flex 3D printing system. 3D printed bonded tungsten is an effective replacement for lead in the medical imaging and aerospace markets, and as such, it is a great solution for protecting people and their environments from the harmful effects of ionizing radiation.

Tungsten Carbide

One of the hardest carbides with a melting point of 2770°C, Tungsten Carbide is mainly used in the production of high wear-resistant abrasives, carbide cutting tools (knives, drills and circular saws), and milling and turning tools used by the metalworking, woodworking, mining, petroleum and construction industries.
